Hmm. I'm not sure the Chinese government would agree with your first statement. They seem to be getting significant US opposition to their technology advancement.
Yes, I'm aware of some of the issues surrounding IP copying. I won't call it theft because the word is contentious and there are those in this forum who don't think you can steal ideas.
I'm also aware of the US' own history of gathering IP to bootstrap its industrial efforts. I guess that "but you did it first" isn't a good defence in law (not really sure of that, after all IANAL) but it makes the US case weaker in my eyes.
